python学习小Demo

练习一 ：拆数字游戏

#coding=utf-8
import random

game_count=0
all_counts=[]
while True:
    game_count+=1
    guess_count =0
    answer=random.randint(0,99)
    while True:
        guess=int(input("猜个数字（0-99）："))
        guess_count +=1
        if guess ==answer:
            print ("恭喜你拆对了")
            print("你一共拆了"+str(guess_count)+"次")
            all_counts.append(guess_count)
            break
        elif guess>answer:
            print ("拆得太大了")
        else:
            print("拆得太小了")
    #必须用raw_input，如果用input，输入时需要打双引号才能识别，识别不了string
    onemore=raw_input("再来一次可好(Y/N)？")
    if onemore !="Y"and onemore !="y":
        print onemore
        print ("舍不得你，下次再来哈")
        print ("您的成绩如下：")
        print (all_counts)
        print ("平均拆中次数"+str(sum(all_counts)/float(len(all_counts))))
        break
    else:
        print("马上再来")
